+// First, copyNestSwagger is required to enable "@nestjs/swagger" in the "nest-cli.json",
+// because nest-cli.json is resolving "@nestjs/swagger" plugin from
+// project's node_modules, but due to dependency hoisting, the "@nestjs/swagger" is located in the root node_modules.
+// Second, we need to run this before starting the application using "nest start", because "nest start" is ran by
+// "nest-cli" with the "nest-cli.json" file, and for nest cli to be loaded with plugins correctly the "@nestjs/swagger"
+// should reside in the project's node_modules already before the "nest start" command is executed.
